FAQs on Fractions Video Lecture - Mental Maths - Class 1
| 1. What are fractions and how are they used in everyday life? |  |
Ans. Fractions are numerical expressions that represent a part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). In everyday life, fractions are used in various situations such as cooking (measuring ingredients), budgeting (dividing expenses), and in construction (calculating dimensions).
| 2. How do you add and subtract fractions? | |
Ans. To add or subtract fractions, they must have a common denominator. If they do, simply add or subtract the numerators and keep the denominator the same. If they don’t have a common denominator, find it by determining the least common multiple (LCM) of the denominators, convert the fractions, and then perform the addition or subtraction.
| 3. What is the difference between proper and improper fractions? | |
Ans. A proper fraction has a numerator that is less than its denominator (e.g., 3/4), while an improper fraction has a numerator that is greater than or equal to its denominator (e.g., 5/4 or 6/6). Improper fractions can also be converted to mixed numbers, which consist of a whole number and a proper fraction (e.g., 5/4 becomes 1 1/4).
| 4. How do you multiply and divide fractions? | |
Ans. To multiply fractions, multiply the numerators together and the denominators together (e.g., 2/3 × 4/5 = 8/15). To divide fractions, multiply by the reciprocal of the second fraction (e.g., 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12, which simplifies to 5/6).
| 5. What are equivalent fractions and how can you find them? | |
Ans. Equivalent fractions are different fractions that represent the same value (e.g., 1/2 and 2/4). To find equivalent fractions, you can multiply or divide both the numerator and the denominator of a fraction by the same non-zero number. For example, multiplying 1/3 by 2 gives you 2/6, which is equivalent to 1/3.
